NSEN Valve tsis ntev los no tau ua qhov nruab nrab ntsev tshuaj tsuag ntawm lub valve, thiab ua tiav kev xeem dhau los ntawm TUV cov pov thawj.Cov xim siv rau lub valve kuaj yog JOTAMASTIC 90, qhov kev xeem yog raws li tus qauv ISO 9227-2017, thiab lub sijhawm xeem yuav kav 96 teev.

Hauv qab no kuv yuav qhia luv luv lub hom phiaj ntawm NSS xeem,

Cov tshuaj tsuag ntsev simulates ib puag ncig ntawm dej hiav txwv los yog kev nyab xeeb ntawm thaj chaw qab ntsev, thiab yog siv los ntsuas cov ntsev ntsev corrosion tsis kam ntawm cov khoom, cov khoom siv thiab lawv cov txheej tiv thaiv.

Cov txheej txheem tshuaj tsuag ntsev kom meej meej qhia cov kev sim ntsuas, xws li kub, av noo, sodium chloride tov concentration thiab pH tus nqi, thiab lwm yam., thiab tseem tso rau pem hauv ntej cov kev cai rau kev ua tau zoo ntawm cov ntsev tsuag tshuaj ntsuam chamber.Cov txheej txheem rau kev txiav txim cov txiaj ntsig ntawm kev ntsuas ntsev ntsev muaj xws li: kev ntsuas ntsuas kev txiav txim, ntsuas qhov ntsuas qhov ntsuas, corrosive tsos judging txoj kev, thiab cov ntaub ntawv txheeb xyuas cov ntaub ntawv txheeb xyuas.Cov khoom uas xav tau ntsev tsuag tshuaj ntsuam yog tsuas yog qee cov khoom siv hlau, thiab kev tiv thaiv corrosion ntawm cov khoom raug tshawb xyuas los ntawm kev sim.

Kev simulated ntsev tsuag ib puag ncig kev sim yog siv ib hom khoom siv kuaj nrog qee qhov ntim qhov chaw-tshav tshuaj tsuag lub thawv, hauv nws qhov chaw ntim, cov txheej txheem tsim khoom siv los tsim cov ntsev tsuag ib puag ncig los ntsuas qhov zoo ntawm cov ntsev tsuag corrosion. tsis kam ntawm cov khoom.Piv nrog rau tej yam ntuj tso ib puag ncig, ntsev concentration ntawm chloride nyob rau hauv lub ntsev tsuag ib puag ncig yuav ua tau ob peb los yog kaum tawm lub sij hawm cov ntsev tsuag cov ntsiab lus ntawm lub ntuj puag ncig, uas zoo heev tsub kom tus nqi corrosion.Kev ntsuas ntsev ntsev ntawm cov khoom yog nqa tawm thiab cov txiaj ntsig tau txais Lub sijhawm kuj tseem luv heev.Piv txwv li, yog tias cov khoom lag luam raug kuaj nyob rau hauv ib puag ncig raug, nws yuav siv sij hawm 1 xyoos los tos nws corrosion, thaum qhov kev sim nyob rau hauv kev simulated ntsev tsuag ib puag ncig tej yam kev mob yuav tsum tsuas yog 24 teev kom tau txais cov txiaj ntsig zoo sib xws.

Qhov nruab nrab ntsev tsuag tshuaj ntsuam (NSS test) yog qhov ntxov tshaj plaws thiab feem ntau siv cov txheej txheem kev ntsuas corrosion.Nws siv 5% sodium chloride ntsev aqueous tov, pH tus nqi ntawm cov tshuaj yog kho nyob rau hauv nruab nrab ntau yam (6-7) raws li cov tshuaj tsuag.Qhov ntsuas kub yog 35 ℃, thiab tus nqi sedimentation ntawm cov ntsev tsuag yuav tsum nyob nruab nrab ntawm 1 ~ 2ml / 80cm²·h.
